Noob with code problem. :P

Question

Hello, I am a beginner in Flash and I have started to pick away at a couple of tutorials, recently I came up with this error in my code and I can´t seem to figure it out.
Error
C:\Users\anton\Downloads\Flash games\interactivestorybook\Main.as, Line 10
1046: Type was not found or was not a compile-time constant: HillPage.
C:\Users\anton\Downloads\Flash games\interactivestorybook\Main.as, Line 11
1046: Type was not found or was not a compile-time constant: PondPage.
package
          import flash.display.MovieClip;
          import flash.events.MouseEvent
          public class Main extends MovieClip
                    var startPage:StartPage
                    var hillPage:HillPage
                    var pondPage:PondPage
                    public function Main()
                              startPage = new StartPage()
                              hillPage = new HillPage()
                              pondPage = new PondPage()
                              addChild(startPage)
                              //Event listeners
                              startPage.hillButton.addEventListener(MouseEvent.CLICK, onHillButtonClick)
                              startPage.pondButton.addEventListener(MouseEvent.CLICK, onPondButtonClick)
          // Event handlers
          function onHillButtonClick(event:MouseEvent):void
                    addChild(hillPage)
                    removeChild(startPage)
          function onPondButtonClick(event:MouseEvent):void
                    addChild(pondPage)
                    removeChild(startPage)
Would appreciate if someone could give me a hand, it is probly just something obvious but at the same time not obvious to me.

Answer 1

I was able to figure out my fatale error, and boy was it an obvious one, forgot to export the symbol to actionscript in the properties panel :/
Thanks for your help !
